Abstract

Based on a semianalytical version of the finite element method, a numerical method has been developed for calculating the stress-strain parameters in three-dimensional, curvilinear heterogeneous prismatic bodies during thermoelastoplastic deformation. Geometric nonlinearity and temperature effects on the physical and mechanical properties of the material are taken into consideration. Numerical study test results are presented which confirm that the suggested method is more efficient than the traditional FEM.
